Directions: From Oklahoma City take I-44 south to Medicine Park/Hwy 49 exit and go west 14 mi. If coming from Lawton, take US62 west to Cache exit and go north 6 miles. Once in the refuge follow the signs to the Refuge HQ. Pass the headquarters and go on to the Dog Run Hollow Trail System (near French Lake)
Trail Information: There are several trails in the Dog Run Hollow. They are designated by signs with different animals. The Buffalo trail is the best and longest (about 8 mi) This is a loop and parking is close by so you can do several. There are shorter loops of about 2 & 1 miles respectively. The trails are a little rocky in parts, by very enjoyable. Have fun, but keep your distance from the buffalo. I have never been charged by one, but wouldn't like to try the experience.
